  • Utilize CloudWatch Alarms for real-time notifications
Monitoring latency metrics for relevant AWS services allows you to diagnose intermittent latency spikes by identifying patterns and trends in response times.

Scenario: You have set up CloudWatch Metrics for various AWS services in your environment. How would you configure CloudWatch Alarms to notify you of potential performance issues or breaches in service-level agreements (SLAs)?

  • Disable CloudWatch Alarms to reduce noise
  • Manually trigger CloudWatch Alarms when issues arise
  • Set thresholds for CloudWatch Alarms based on performance metrics
  • Use CloudWatch Events to trigger Alarms based on scheduled intervals
Setting thresholds for CloudWatch Alarms based on performance metrics allows you to proactively detect potential performance issues or breaches in SLAs and receive notifications for timely intervention.
